Question

Please Help Me!!! I don’t understand.

Answer 1

B (4, 1)

Explanation:

When you rotate 90 degrees about the origin you do (x,y) ----> (y, -x)

So let's do that first to your points.

(-4, 1) -----> (1, 4)

Now we have to do y = x you do this (x,y) ---> (y, x)

All we have to do now is switch them again.

(1, 4) ----> (4,1)

Hope this helps ya!!
